following is a specification. v

My present invention relates' generally to upholstery and morepai-ticularly to up-v holstery of an inlatabletype, the object of myinvention being to provide strong and durable cushion pads applicable tovarious uses including the seats and backs of variousarticles offurniture and vehicles and also capable of utilization in the form of anindependent cushion. v

My invention is capable of various forms,

, certain of which are shown in the accomthis specification,

panying drawings, which form a part of and in which-- Figure lis a view.partly in plan and-partly broken away and in section illustrating arectangular multi-celled cushion constructed in accordance with myinvention. j Fig. 2 is a vertical section on a substantiallyenlargedscale taken therethrough on substantially line 2-2 ofF ig. l. Fig. 3 isa vtransverse sectional view taken therethrough substantially on line3-3 of Fig. l. Fig. 4 is a view similar to Fig. l illustrating the useof a plurality of independent filling channels in connection,

with a rectangular cushion of a multi-celled type. Fig. 5 is a similarview illustrating the cushion shown in Fig. 4, with a surroundingflange, and Fig. 6 is a vertical section, taken on an enlarged scale,vthrough a portion of Fig.l 5, substantially on line 6-'6 of saidfigure.

Referring now to these figures and particularly to Figs.l 1, 2 and 3, I'provide a generally rectangular Icushion A, the body of which is formedof a yplurality of parallel rows of inflatable cells, each of which rowsis separated by an air channel B and each of which cells is generallytriangular in form, it being particularly noted that the cells of eachrow or Yseriesare alternately reversed with respect to one another,alternate cells C having their apices opening in onedirection and theother cells C having their apices opening in relatively oppositedirections. The'body of the cushion so formed is surrounded by acontinuous rib D, the end portions and one side portion of which arerespectively provided with air channels D Texas, have invented an'Improvement in'Upholstery, of which the on al similarly enlarged scaleand D2 and to one corner of which is connected a filling valve D3 ofsuitable type. Thus the several cells of the several rows thereof,opening in alternately opposite directions, are 1n communication withthe sevthese several chanof the cushion as eral channels B and D, nelsopening at one side particularly seen in Fig. l, into the main airchannel D2 at one end of which the filling valve D3 is connected.

In Fig. 4 practically the same arrangement of the rows of cells E and Eis carried out together with the surrounding rib F with its end channelsF and the intermediate channels G between the several rows of cells areeach extended at`one side of the f pad and provided with an independentlilling valve F2 and G.

In Fig. 5 the arrangement shown in Fig. 4: is duplicated with theaddition of a flat surrounding iiange Gr2 beyond the surrounding rib F,as more clearly shown in the detail F ig.v 6.

Thus from the foregoing Vit will be seen that my invention provides asimple and' compact inflatable cushion which will be at once strong anddurable and in which the usual disadvantages of puncture are practicallyeliminated. Various flexible materials impervious to air are suitable inthe formation lof the cushion thus shown and described and it is to beunderstood that as to material, size and general outlines the cushionsare to be formed as best seems to accord with the ultimate use in mind,either lined or unlined, covered or uncovered, tufted or untufted, asdesired. Y

I claim: e

l. A flexible inflatable cushion of the character described, the .bodyof which has a surrounding rib provided in relatively opposite portionsthereof with air channels, the said body of the cushion having a seriesof spaced air channels Yparallel with the said air channels of the riband also provided in acter described, the body of which has asurrounding rib and a plurality of rows of oppositely opening triangularcells and parallel air channels between and along the se- 5 ries of aircells and in communication with alternate cells of adjacent rowsthereof, and certain of which air channels are formed in portions of thesurrounding rib, together with means for admitting air to the several 10air channels, all as set forth.

3. A flexible inflatable cushion ofthe charair channels.

acter described, the body of which has a surrounding rib and consists ofa plurality of rows of oppositely opening triangular cells and airchannels communicating with alter- 15 nate cells of adjacent rowsthereof, together with means for admitting air to the several LAURA L.DODD. Witnesses:
